FactorEngine: A Knowledge‑Infused Framework for Quantitative Alpha Factor Discovery
The paper introduces FactorEngine, a program‑level factor mining system that injects domain knowledge from financial reports via LLM‑guided pipelines, separates logic correction, parameter optimization, and LLM usage, and demonstrates superior information‑ratio, Sharpe, and annualized returns over GP, neural, and other agent‑based baselines on CSI300 and CSI500 markets.
